Li Feng had been waiting on the top of the tree for more than twenty minutes, because this was the most conservative and safest method, so he first used this kind of waiting-to-be-waiting wait. During this period, some abilities guarding the periphery obtained communication assistance with Li Feng.

There was a constant question on the other side to ask whether Li Feng needed anything, and there could be excavation equipment to help. Li Feng refused all of these, just kidding, those equipment were so slow to move, and the ground fish moved faster than normal fish in the water. It was a bit whimsical to catch monsters with this thing, and it was more like a person giving away a head. I was afraid that it wasn't just digging here, but it jumped up and ate all the people and machines.

However, after Li Feng refused, these people always wanted to help and kept asking if they needed support. In the end, Li Feng was a little impatient and asked them to hide in the distance and watch honestly. Don’t make trouble, learn more about how to defeat monsters, which is the greatest help to themselves.

Although Li Feng said rudely, the height of Li Feng was convinced by those people. So they did not continue to get entangled, but instead found an excellent place and then took props similar to telescopes to watch them at a distance.

Li Feng continued to wait, but after waiting for a long time, he did not see even a small ground fish appear. It seems that these guys are interested in lurking underground and do not want to come up unless prey appears.

Then the first combat idea of ​​a surprise attack on the site failed with the passage of time.

The problem is not big. This is what I want tolerate mistakes, and it is not a big deal except for delaying some time. Then you should gradually try risky practices, from relatively safe to gradually dangerous to see which one can work.

Li Feng, who was on the top of the tree, took out his magic wand and released some more powerful magic to attack the velociraptor-like creatures on the ground. Killing these was originally just a small spell such as ice cone. He deliberately made a louder sound, and it depends on whether these ground fish reacted on the ground to attack.

The rumbling sounded, and Li Feng used a larger magic to kill these monsters. Although it was not like cannons to kill mosquitoes, there was not much difference in output ability.

"These monsters should feel honored that this magic will face a height that they will never climb in their entire lives."

Li Feng muttered in his heart, and the movements in his hands did not stop.

After a violent bombardment, the shattered corpses of monsters remained on the ground, and there was obviously no one who was alive.

Continue to concentrate on observing the ground, but Li Feng was still disappointed. The monsters swim a little faster, and they stayed on the corpses of these monsters from time to time for a while, but they did not appear from the earth in the end.

Li Feng had two considerations in this experiment. One was to attack to see if the ground fish would appear, and the other was to see if the monster corpse was used as food bait, and whether the ground fish would appear. Obviously, both of these were to make the ground fish notice to a certain extent and had plans to come out. But in the end, they did not jump out of the earth. Both strategies had certain effects, but they still failed in the end.

There is no way, I will pass on this combat idea again and go to the next step.

The next step should be to place some live livestock to see if they can be drawn out. The monster's corpses cannot attract them. Perhaps they are all from the same place and there is no clear reason for the swallowing relationship.

Then if you place some livestock and poultry, ranging from chickens to cattle and sheep, it is very likely to attract the attention of these fish. However, this idea is good, but the reality is difficult to achieve.

Just talking about the current situation, I am alone here, so there is no bait to use. The sunset is setting, and Li Feng doesn’t want to delay too long. Even if he teleports and applies for withdrawal, it will be quite troublesome.

This method can only be skipped and continue with the next method.

In fact, all the way to the end, Li Feng was sure to jump to the ground and use it as bait. When he was making bait, the monsters showed the greatest sense of appearance, because they would attack creatures on the ground. Especially the abilities contained a certain amount of energy in the body, which was the food that these monsters liked very much.

After all, you are a bait and you have the confidence to make the ground fish appear, but the risk will also be increased to the highest level. Even if you have life-saving methods such as speechless protection and flashing, you will never dare to try this easily.

Then, my next method is...sonic attack!

This is something that Li Feng had some sudden ideas and some practical cases.

The initial inspiration was that I once played a game where there were monsters wandering in the desert. The monsters felt sensitive and solid sound transmission effect, and used a violent sonic boom to make the monsters feel severe pain. This led to pain coming out from the ground and stay away from the solid with excellent sound transmission effect.

If this is just a whimsical idea in the game, Li Feng also found such an example in the archives of Blue Star. Some monsters lurk in some entities. From being common in the land, to various trees and stones.

The monsters of these siege are basically inseparable from several methods. The first is to destroy them together with the container, which is the most straightforward method. If you cannot destroy the container, you will use smoke or chemical reagents to flood the target, making the target feel pain and unable to continue to stay in it. When these cannot be done, the last method is used more frequently, sound wave attacks.

Sound wave attack, to put it bluntly, is a burst of sound, and the powerful volume audio stimulates the monster's hearing.

This kind of creature that survives in various solids all year round usually has a serious visual degeneration. But on the contrary, the hearing is generally very developed to detect the surrounding prey and natural enemies. Therefore, the sound wave attack generally has a very good effect on this monster, which will make the monster directly forced to leave the current place due to unbearable pain in the ear.

As for whether the ground fish under my feet have developed hearing or whether their tactics work, it can only be determined by the results.

After thinking about it, Li Feng immediately took out a prop with a unique shape from his space backpack.

This is an oversized speaker that is nearly two meters long, with an exaggerated shape. One end is very narrow, which is the size of a human mouth. The other end is so big that it is scary, with a diameter of about two meters.

This thing was a coincidence and was purchased with the recommendation of the article. It is essentially a speaker, but it is a super-strong type. It is expensive because the material is very good and can withstand a large number of hits. What's more important is that it contains a large number of magic circles that amplify the sound. Yes, this speaker is actually the kind of command used by the squad or army.

Squads can use this to convey information or locate orders when they are used, such as scattered too far away, and in the army, this kind of thing can also be used to issue orders.

Li Feng once used it, and the effect is very good. If the user does not bring anything to protect his ears, the periosteum may be shaken by the enlarged sound. However, even if the effect is so good, not many people use this thing. Because there are other communication methods, it is also very simple and convenient. This is too huge and heavy, and it is difficult to carry, so naturally not many people buy it.

Because Li Feng had the magical thing of space backpack, he bought it and asked Li Feng to take it with him. With the mentality of not being afraid of ten thousand but being afraid of if, maybe he would use it at any time.

Now, I have used this prop. When Li Feng thought of Cheng Mingli's appearance, he couldn't help but think that he really had a foresight.
